"Marvin Wilson, sanitarium orderly: [Reading from a dictionary] "P-O-O-K-A. Pooka. From old Celtic mythology, a fairy spirit in animal form, always very large. The pooka appears here and there, now and then, to this one and that one. A benign but mischievous creature. Very fond of rumpots, crackpots, and how are you, Mr. Wilson?" [Inverts and shakes the dictionary] "How are you, Mr. Wilson?" Who in the encyclopedia wants to know?"
